  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • Gas Mass Flow Control: Why Thermal Mass Flow Technology is Recommended for Best Accuracy!

    It’s no secret. Price, but perhaps more importantly, performance, drive every new product acquisition you make.  How important is measurement accuracy and control to your lab experiment or industrial process? It’s critical.  If your flow readings are off or the flow is not controlled with precise accuracy your research is compromised, product quality suffers, and processes ...

  • Installation of Radar Level Instruments in Anaerobic Digesters

    ABSTRACTThere are numerous well-proven options available for level determination instrumentation. Instrumenting treatment processes present some unique challenges. Some of these include the ability for wastewater or residuals to clog and blind instruments. Level determination in an anaerobic digester presents these problems as well as others including foaming, surface agitation, and operation in ...

  • Gas Mass Flow Metering - Innovations Promise More Economical Choices- White Paper

    Introduction As the drive towards energy independence in the United States continues at full speed, oil and gas companies are turning to hydraulic fracturing to increase production. Increasingly stringent state and national regulations for flare gas in particular now require the installation of mass flow measurement instruments to measure waste and excess gases burned off as a result ...
